| 1 | 应用电容电阻模型研究大型成熟油田井间连通性显示文摘针对电容电阻模型在大型成熟油田应用时存在的问题,选用了生产井电容电阻模型(CRMP),提出了其在大型成熟油田的简化应用方法,并进行了实例分析。结合大型成熟油田的特征,给出了CRMP简化推导方法。通过优化求解方法缩短求解时间、提高收敛速率,包括应用全局优化算法,计算CRMP目标函数的解析梯度向量及Hessian矩阵并应用于解算器中,进行参数缩放等,使CRMP可以应用于大型油田。通过逐步历史拟合可提高CRMP模拟结果的可靠性。实例分析结果表明,采用该方法得到的连通性分析结果与生产实际相符,验证了该方法的可靠性。根据CRMP模拟结果,可以有效分析注入井与其周围生产井的连通性,并进行相关分析,例如判断哪些注水井可以改注二氧化碳以及某二氧化碳注入井是否适宜注二氧化碳等。 | JAMALI Ali ETTEHADTAVAKKOL Amin | 2017 | 石油勘探与开发2017，44，1： | 5 |
| 2 | Use of 2-(tert-butoxy)-N-(3-carbamothioylphenyl)acetamide and graphene oxide for separation and preconcentration of Fe(Ⅲ),Ni(Ⅱ),Cu(Ⅱ) and Zn(Ⅱ) ions in different samples显示文摘A simple and selective method using a column packed with graphene oxide(GO) as a solid phase extractant has been developed for the multi-element preconcentration of Fe(Ⅲ),Ni(Ⅱ),Cu(Ⅱ) and Zn(Ⅱ)ions prior to flame atomic absorption spectrometric determinations.The method is based on the sorption of mentioned ions on synthesized GO using 2-(tert-butoxy)-N-(3-carbamothioylphenyl)acetamide as a chelating agent.Several parameters on the extraction and complex formation were optimized.Under the optimized conditions(pH 6,flow rate 9 mL/min),metal ions were retained on the column,then quantitatively eluted by HNO3solution(5 mL,3.0 mol/L).The preconcentration factor was calculated as250.The detection limits for the analyte ions of interest were found in the range of 0.11 ng/mL(Ni2+) to0.63 ng/mL(Cu2+).The column packed with GO was adequate for metal ions separation in matrixes containing alkali,alkaline earth,transition and heavy metal ions. | Mohammad Reza Pourjavid Ali Akbari Sehat Majid Haji Hosseini Mohammad Rezaee Masoud Arabieh Seyed Reza Yousefi Mohammad Reza Jamali | 2014 | Chinese Chemical Letters2014，25，5： | 2 |

| 4 | Experimental investigation of the effects of shrub filter strips on debris flow trapping and interception显示文摘Ecological engineering plays an increasingly significant role in mountain hazard control,but the effect of species selection and arrangement(e.g.,row spacing and stem spacing)on debris flow suppression is still unclear.To further understand the interception efficiency of shrub arrangement parameters on debris flow and explore the difference with slow hydraulic erosion,sixteen sets of small-scale flume experiments with different stem and row spacings were done to study the effects of shrubs on debris flow severity,flow rate,velocity,and particle size.The results suggest that,for a dilute debris flow,sediment interception effectiveness(27.4%-60.9%)decreases gradually as stem spacing increases.Moreover,as row spacing increases,flow velocity reduction(34.4%-44.9%)and flow reduction(18.5%-47.4%)gradually decrease;and the bulk density reduction(0.5%-5.3%)and sediment interception increase initially and then decrease.In contrast,for a viscous debris flow,the flow reduction,flow velocity reduction,and sedimentation interception decrease gradually as the stem spacing increases.As row spacing increases,the flow velocity reduction,flow reduction,and sediment interception all increase initially and then decrease.A formula for the flow velocity of dilute debris flow after the filter strip was derived based on the energy conservation law and Bernoulli’s equation,confirming that debris flow movement is closely related to the degree of vegetation cover.This research strengthens the current understanding of the effectiveness of vegetation in debris flow disaster prevention and control and can guide practical applications. | Songtang He Wenle Chen Daojie Wang Xiaoqing Chen Yuchao Qi Peng Zhao Yong Li Yongming Lin Ali Akbar Jamali | 2023 | International Journal of Sediment Research2023，38，2： | 1 |

| 6 | Experimental evaluation and modeling of liquid jet penetration to estimate droplet size in a three-phase riser reactor显示文摘In this work,the effects of injecting an evaporating liquid jet into solid–gas flow are experimentally investigated.A new model(SHED model) and a supplementary model(spray model) have also been proposed to investigate some flow-field characteristics in three-phase fluidized bed with the mean relative error 4.3% between model and measured results.Some experiments were conducted to study the influences of flow-field parameters such as liquid volumetric flow rate,injection velocity,jet angle and gas superficial velocity as well as solid mass flux on the jet penetration depth(JPD).In addition,independent variables were experimentally employed to propose two empirical correlations for JPD by using multiple regression method and spray cone angle(SCA) by using dimensional analysis technique.The mean relative errors between the JPD and SCA correlations versus experimental data were 7.5% and 3.9%,respectively.In addition,in order to identify the variable effect,a parametric study was carried out.Applying the proposed model can avoid direct use of expensive devices to measure JPD and to predict droplet size. | Ali Akbar Jamali Shahrokh Shahhosseini Yaghoub Behjat | 2016 | Chinese Journal of Chemical Engineering2016，24，2： | 1 |

| 8 | Encoder-Decoder Based LSTM Model to Advance User QoE in 360-Degree Video显示文摘The development of multimedia content has resulted in a massiveincrease in network traffic for video streaming. It demands such types ofsolutions that can be addressed to obtain the user’s Quality-of-Experience(QoE). 360-degree videos have already taken up the user’s behavior by storm.However, the users only focus on the part of 360-degree videos, known as aviewport. Despite the immense hype, 360-degree videos convey a loathsomeside effect about viewport prediction, making viewers feel uncomfortablebecause user viewport needs to be pre-fetched in advance. Ideally, we canminimize the bandwidth consumption if we know what the user motionin advance. Looking into the problem definition, we propose an EncoderDecoder based Long-Short Term Memory (LSTM) model to more accuratelycapture the non-linear relationship between past and future viewport positions. This model takes the transforming data instead of taking the direct inputto predict the future user movement. Then, this prediction model is combinedwith a rate adaptation approach that assigns the bitrates to various tiles for360-degree video frames under a given network capacity. Hence, our proposedwork aims to facilitate improved system performance when QoE parametersare jointly optimized. Some experiments were carried out and compared withexisting work to prove the performance of the proposed model. Last but notleast, the experiments implementation of our proposed work provides highuser’s QoE than its competitors. | Muhammad Usman Younus Rabia Shafi Ammar Rafiq Muhammad Rizwan Anjum Sharjeel Afridi Abdul Aleem Jamali Zulfiqar Ali Arain | 2022 | Computers, Materials & Continua2022，，5： | 0 |
